Science Fun – Color Mixing

Mixing Colored Water

Ask your adult assistant to help you find somewhere to set up your science lab. Protect surfaces and clothing as appropriate before undertaking science experiments. Safety glasses are also included to protect eyes from splashes, as needed.  Adult supervision is required at all times whilst undertaking experiments.

First of all you need to make your colored water! You will need test tubes or cups / jars, color tablets (blue, yellow and red) or food coloring and water. We used color tablets which are slightly lower mess that food coloring!

  1. Fill three test tubes or cups with water until around 3/4 full.
  2. Open the packet of color tablets and take out one of each color (with dry hands) or if using food coloring, add a few squirts (remember that food coloring will stain skin, surfaces and clothes).
  3. Take a minute to talk about what you’re going to do. Now write down or ask your adult assistant to note your hypothesis in your notebook. What do you think will happen to the water when you add a tablet?
  4. Place a blue tablet (or coloring) in one test tube, a yellow tablet (or coloring) in one test tube and a red tablet (or coloring) in one test tube.
  5. What’s happened? Where has the color tablet gone? Check back in your notebook; was your hypothesis correct?

 

What happened?

If you used color tablets – you dissolved your color tablets in the water. You can’t see the tablets anymore but they are still there. You know they are still there because they changed the color of the water.  You made a solution! Did you see your tablets fizzing? You made a chemical reaction.  Wow! You are an amazing scientist.

 

Color Mixing

You will need your lab set up with the colored water as above, a pipette, empty plastic cups and a cup of water.

  1. Practice using your pipette by placing it into a cup of water and squeezing the bulb at the end. Did you see bubbles come out? Let go of the bulb. Do you see the water going up the pipette? Take it out, place it into an empty cup and squeeze the bulb again. Whoosh! Did the water squirt out? Pipettes are used by scientists to carefully measure liquids in their experiments.
  2. Now try again but squeeze the bulb first before putting it into the water, keep holding it and then lower in carefully into the water. Practice until you feel happy using the pipette.
  3. Use your pipette to draw up the blue colored water and add it to an empty cup. Rinse your pipette in the cup of clear water then draw up some yellow colored liquid and add it to the same cup. What happened? You made green!
  4. Repeat with the other colors of water. What two colors make purple? Can you make orange?
  5. How many different colors can you make? Don’t forget to mix the new colors you made too!
  6. Don’t forget you can draw or note your observations in your notepad.

How Does It Work?

Red, yellow and blue are primary  colors. By mixing them together you can make lots of different kinds of colors.
